A casino is a gambling establishment, usually with a variety of games for people to try their luck at. It may also have a restaurant, bars, and entertainment. In order to gamble in a casino, people must be of legal age and obey the rules and regulations of the establishment.

Casino games include all kinds of table games, such as poker and blackjack, and slot machines. They also include games of chance, such as baccarat, chemin de fer, and roulette. Some casinos also have sports betting.

A successful casino brings in billions of dollars each year to the companies, investors, and Native American tribes that own and operate it. It also helps local governments bring in taxes and fees. Some states have banned casino gambling, while others allow it only in a limited manner, such as on riverboats.

In the United States, there are now more than 1,000 casinos. The largest are in Las Vegas, Nevada, and Atlantic City, New Jersey. In addition to traditional land-based casinos, there are now many online casinos.

Casinos often employ large numbers of employees. Despite this, they are not immune to the problems of employee theft and dishonesty. The need to protect the assets of the casino from such problems is one reason why it is important for casinos to have security cameras. It is also important to hire honest and competent personnel. Statistical deviations from expected values, which are detectable by knowledgeable employees, can be used to identify suspicious activity.
